As long as in addition, technical characteristic involved in the utility model different embodiments disclosed below is each other Not constituting conflict can just be combined with each other.

Embodiment 1

The present embodiment is specifically described below in conjunction with the accompanying drawings：

The present embodiment provides a kind of safety socket as Figure 1-10 shows, including:Socket casing 1 and locking mechanism, it is described Graphite holder 3 is provided with Socket casing 1, the surface counter electrode holder 3 of Socket casing 1 is provided with three and inserts jack；The locking Mechanism includes：The first sliding block shelves part 4 for blocking L poles and N poles, the power that is squeezed effect is stepped down, and makes plug and the L poles, N poles It can connect；Elastic reset blocks the L poles and N poles after extruding force disappears；Work as part with the second sliding block for blocking earthing pole 5, the power that is squeezed effect is stepped down, and plug and the earthing pole is connected；Elastic reset blocks described connect after extruding force disappears Earth polar；Also include button parts 6, can be pressed to motion in Socket casing 1, the button parts 6 respectively with first sliding block Block piece 4 and the second sliding block block piece 5 are formed with the first position limiting structure and the second position limiting structure, first position limiting structure and/ Or second position limiting structure stops that the button parts 6 moves into Socket casing 1, to limit described in plug is further inserted into Socket casing 1；Or after the first sliding block block piece 4 and the second sliding block block piece 5 are stepped down by the effect of plug extruding force, to release The stop of the first position limiting structure and the second position limiting structure to the button parts 6 is stated, to insert in Socket casing.

Above-mentioned embodiment is the core technology scheme of the present embodiment, by set have to block respectively L, N pole and Earthing pole and can elastic reset the first sliding block block piece 4 and the second sliding block block piece 5, and respectively with the first sliding block block piece 4 And second button parts for being formed with the first position limiting structure and the second position limiting structure between sliding block block piece 5, set by this structure The logical relation to be formed and mutually restricted is put, with multiple-protection effect, first by the first sliding block block piece and the second sliding block block piece Sheltering from jack position can prevent foreign matter, finger etc. to be directly protruding into jack；It is spacing secondly by the first position limiting structure and second Structure barrier button parts are pressed in housing and moved, and can play the work that limitation plug is further inserted into the Socket casing With only simultaneously when the first sliding block block piece 4 and the second sliding block block piece 5 are squeezed resigning, can releasing and button parts 6 transported The locking of action, compared with prior art, can avoid the situation that in non-matching plug insertion socket and plug half is inserted from occurring； Furthermore, stretch into Socket casing when there is foreign matter to extrude any sliding block block piece, its socket internal circuit is not turned on, and can effectively be prevented Electrocution conditions occur.Therefore, safety socket of the present utility model can prevent the insertion of non-matching plug, got an electric shock with anti-mis-insertion etc. Effect, reasonable in design, easy to use, security is more reliable, reaches the purpose of safe handling.

Make further preferred according to above-mentioned embodiment, in addition to touch-control loop mechanism, it includes the first conductive part and the Two conductive parts；Wherein described first conductive part sets the bottom of Socket casing 1, and is connected with the graphite holder 3；Described Two conductive parts are arranged on the second sliding block block piece 5 and corresponding with first conductive part, and the second sliding block block piece 5 is stepped down When, second conductive part 8 and the conductive part are abutted against.By setting corresponding first conductive part and the second conductive part, when When second sliding block block piece 5 is stepped down, drive the second conductive component and the first conductive component to abut against and connected with forming circuit, and the When two sliding block block pieces 5 reset, automatic shutoff circuit plays the incorrect insertion of plug or made when having foreign matter insertion without turning circuit With therefore the effect with protection against electric shock, when also the plug of only matching is correctly inserted into, just can provide power supply to plug and use, have There is safe and reliable advantage.

Need explanation make, although the locking mechanism in the present embodiment provide the first sliding block block piece 4, the second sliding block block piece 5, And the fit form of button parts 6, set with two position limiting structures for stopping button parts action, non-same specification can be stopped Plug is inserted in jack or plug half inserts the form of connection, it is clear that can also be in the first sliding block block piece 4, the second sliding block block piece The latch-up structure of the first lockhole for having lock function to the button parts and the second lockhole is set respectively on 5, to play lock Determine the effect of button parts action, i.e., after first sliding block shelves part 4 and second sliding block shelves part 5 is squeezed resigning respectively, the One lockhole and the alignment of the second lockhole, so that button parts 6 can be pressed to motion in Socket casing 1, and are stretched under aligned condition First lockhole and the second lockhole.Those skilled in the art can as described above to locking mechanism specific setting side Formula is selected, and other equivalent embodiments of locking mechanism is not repeated one by one then at this.

3-10 elaborates to first position limiting structure and the second position limiting structure of the present embodiment below in conjunction with the accompanying drawings：

The receiving hole suitable for the activity of button parts 6 is formed on the Socket casing 1, the button parts 6 include The touching indication end 61 stretched out outside the surface of the Socket casing 1, and the insertion end 62 that relatively described touching indication end 61 is set, And deviate from the spacing block face 63 of the receiving hole positioned at button parts 6 described in the underlying barrier of touching indication end 61.Wherein The lock-out state indicated when stretching Socket casing 1 in touching end 61 is outer for safety, therefore, with reminding user to distinguish, socket is The no state in safety, security is more reliable.

As a preferred embodiment, first position limiting structure includes：It is arranged on the first sliding block block piece 4 The first stopper section 41, take shape in arch steps corresponding with first stopper section 41 on the touching indication end 61, First sliding block shelves part 4 be not squeezed resigning when, the arch steps are resisted against on first stopper section 41.Further It is preferred that, second position limiting structure includes：The second stopper section 51 on the second sliding block block piece 5 is arranged on, and takes shape in institute State step cutting pattern corresponding with second stopper section 51 in insertion end 62, the second sliding block shelves part 5 is not squeezed resigning When, the step cutting pattern is resisted against on second stopper section 41.In summary, the first position limiting structure is by the first stopper section and touches Arch steps on indication end are cooperatively formed, identical, and the second position limiting structure is circular on the second stopper section 41 and insertion end Step is cooperatively formed, and this position limiting structure mutually kept out is set, and its is simple in construction, is coordinated reliable, is made with dual stop With when the first sliding block block piece 4 and the second sliding block block piece 5 are not stepped down, i.e., in the state of not unlocking, effectively stopping button parts Moved in the case of compression into Socket casing, it is ensured that the security that socket is used.
